另一个答案将非常相似，但不需要设置TextView的文本两次

TextView TV = (TextView)findViewById(R.id.mytextview01);

Spannable wordtoSpan = new SpannableString("I know just how to whisper, And I know just how to cry,I know just where to find the answers");        

wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

TV.setText(wordtoSpan);

通过传递String和Color在文本上设置颜色:

private String getColoredSpanned(String text, String color) {
  String input = "<font color=" + color + ">" + text + "</font>";
  return input;
}

通过调用下面的代码设置TextView / Button / EditText等文本:

TextView:

TextView txtView = (TextView)findViewById(R.id.txtView);

获取彩色字符串:

String name = getColoredSpanned("Hiren", "#800000");

在TextView上设置文本:

txtView.setText(Html.fromHtml(name));

Done

这里有些答案不是最新的。因为，您将(在大多数情况下)在链接上添加一个自定义的clic操作。

此外，正如文档帮助所提供的，您的跨接字符串链接颜色将有一个默认颜色。 默认的链接颜色是主题的强调色或android:textColorLink(如果这个属性是在主题中定义的)。

这里有一种安全的方法。

 private class CustomClickableSpan extends ClickableSpan {

    private int color = -1;

    public CustomClickableSpan(){
        super();
        if(getContext() != null) {
            color = ContextCompat.getColor(getContext(), R.color.colorPrimaryDark);
        }
    }

    @Override
    public void updateDrawState(@NonNull TextPaint ds) {
        ds.setColor(color != -1 ? color : ds.linkColor);
        ds.setUnderlineText(true);
    }

    @Override
    public void onClick(@NonNull View widget) {
    }
}

然后使用它。

   String text = "my text with action";
    hideText= new SpannableString(text);
    hideText.setSpan(new CustomClickableSpan(){

        @Override
        public void onClick(@NonNull View widget) {
            // your action here !
        }

    }, 0, text.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
    yourtextview.setText(hideText);
    // don't forget this ! or this will not work !
    yourtextview.setMovementMethod(LinkMovementMethod.getInstance());

希望这对你有很大帮助!

有一个用于创建Spannable的工厂，并避免强制转换，就像这样:

Spannable span = Spannable.Factory.getInstance().newSpannable("text");

设置你的TextView的文本跨度，并为你的文本定义一个ForegroundColorSpan。

TextView textView = (TextView)findViewById(R.id.mytextview01);    
Spannable wordtoSpan = new SpannableString("I know just how to whisper, And I know just how to cry,I know just where to find the answers");          
wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);    
textView.setText(wordtoSpan);

您可以在Kotlin中使用扩展函数

fun CharSequence.colorizeText(
    textPartToColorize: CharSequence,
    @ColorInt color: Int
): CharSequence = SpannableString(this).apply {
    val startIndexOfText = this.indexOf(textPartToColorize.toString())
    setSpan(ForegroundColorSpan(color), startIndexOfText, startIndexOfText.plus(textPartToColorize.length), 0)
}

用法:

val colorizedText = "this text will be colorized"
val myTextToColorize = "some text, $colorizedText continue normal text".colorizeText(colorizedText,ContextCompat.getColor(context, R.color.someColor))
viewBinding.myTextView.text = myTextToColorize
